js中的继承

<script>

//js中的继承

function Animal(){

this.kind = "animal";

}

Animal.prototype.type = "water";

//绑定构造函数，原型中的属性和方法不会被继承。

function Cat(Name,Color){

this.Name = Name;

this.Color = Color;

Animal.apply(this.arguments);

}

var cat = new Cat("tom","watth");

console.log(cat);

//原型指向父类对象,继承父类中的所有属性和方法，包括原型中的内容

function Animal(){

this.kind = "animal";

}

Animal.prototype.type = "water";

function Cat(name,Color){

this.name = name;

this.Color = Color;

}

Cat.prototype = new Animal();

var cat = new Cat("tom","white");

console.log(cat);
